PIPE OR HOS E COUPLING.

ToaIZ whom it may concern:

Be it known that I. Jonx Htcxnv PHIL- L1rs,Jr.. a citizen of the United States. residing in the city a nd county of Jackson, State of Michigan. have invented certain new and useful lm n-ovements in Pipe or .Hose Couplings. of which the following is the coupling and uncoupling of the cars;

second. to provide an improved coupling in which the pressure within the pipe. or pipes coupled. tends to hold the coupling members together rather than to separate them: third. to provide an improved coupling .for the Pil). of railway trains which may be readily attached to the cars and readily adjusted to cars of ditferent construction and heights: fourth, to provide an improved coupling which is very simple in construction and very durable in use. the wear thereon being very'slight; fifth, to provide an improved coupling for the pipes of railway trains in which a car equippedwith a combination coupler may be reatily coupled or connected to a car equipped with individual couplings: sixth. to provide in a coupling an improved packing ring; seventh. to provide in a coupling an improved 0ll.-[ll1(f1l0ll and arrangement. of parts which may he very quickly as sembled or disassembled in tmtnufacture, 0r

for the purpose of renewing the parts.

Further. objects. and objects relating to structural details. will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in "the following specification.

In the drawing, the sectional views are taken looking in the direction of the'little arrows at the ends of the-section lines. and similar numerals of reference refer to similar parts throughout the several views- Referring to the drawing, 1-1 represents the end sills or frame pieces of a pair of rail way cars; 2 the draw bars; and 3 the drawheads thereof. The pipe sections-1, and 6 j are the air. air-brake and steam pipes, re-

spectively, of the cars. The steam pipe 0 is preferably a flexible hose, while the pipes 4 and 5 are ri id and connected to the aims of the cars by suitable flexible joints, preferably such as I have illustrated in myapplication for Letters Patent filed July 26, 1907, Serial No. 385,716, the details of this connection not being here illust 'ated; 5 Each set of pipe sections is provided with a coupling member, comprising a head T having a forwaidly-projecting tapered male member 8 at one side, and a corresponding tapered female member or socket 9 at the 10 other side adapted to receive the male member of the opposite. head. The members 8 are preferably provided with an outwardly facing catch 10 at their outer ends with which the pivoted latches ll engage when the heads arejbrought' into. their coupled relation. These latches 11 are held in their engaging position by means of the springs 12.

The inner ends of the female members 9 are preferably open to receive the catch portions 10 of the male members, as illustrated in Fig. 3. The inner walls of the members 8 and 9 are preferably flattened, and are preferably arranged to lie in the same plane to form the facesof the coupling heads, the faces being inclined to the longitudinal axis of the heads. By; this arrangement, when the heads are brought togethe r-owing to the shape of themembers S and 9'-the faces are clamped against each other with a wedge- '20 like action.

The members 8 are provided with flangelike stops l3 attheir rear ends which limit their forward movement, thereby bringing the packing rings into proper relation. The passages lat ofthe coupling heads are preferably arranged to deliver at an angle to the longitudinal axis'of the heads, so that the pressure within the pipes tends to hold the heads together rather than to separate the 40 same, that is, it tends to hold the catch and their latch members in engagement; at the same time, the heads readil separate when pulled rearwardl as in the uncoupling of the cars to which they are attached.

5 The coupling members are preferably supported by hangers consisting of-the draw bar clips 15, the angle or L-shaped bars 16, and the hanger plates 17, through which the pipe sections 4 and?) are arranged. The angle 5 bars 16 are adjustably secured to the clip pieces 18 and the hanger plates 17 by means of suitable screws l9, so that the hangers may be adjusted to bring the coupling members into proper position on cars of dill'erent sizes or build.

The holes 20 and 21 in the hanger plates, through which the pipes at and 5 are arranged, are preferably of suitable size and shape so that the pipes may swing laterally therein.- They are also of suflieient 'size so that the heads- '7 have a slight vertical movement. The pipes are provided with collars .2'2 and 23. arranged to the rearol' the hanger platcs to liniit their forward movement. The coupling members are held yielding-1y for Letters Patent above refered to.

forward by means of the coiled springs 24 These springs are preferably of the spiral, t vpe and arranged about. the pipe sections 5, suitable seats, as being provided in the hanger plates for the base of the-springs, and collarsQtJ being arranged on'the pipes 5 to receive the thrust of the springs. The seats 25 are inclined slightly so that the springs not only hold the heads yie-ldingly forward. 'buthold them in substantially a horizontal position as well,-tha't is, these springs have a slight upward lift which counter-lntlances the weight of the heads. \l'hen a pair of cars equipped with thesecoupliug members is'brought together, the 30 heads are guided by means of the members 8 and 9 into proper relationl The members are preferably tapered-as stated. s0 that the facts of the heads are brt'tught together with a wedge-like or clamping action. 35

The packing rings '27 for the pipes are preferablv rubber, or a suitable yielding composition, the heads being provided with suitable seats to receive the same. These packing rings normaly project slightly be no yond the faces ofthe heads, so that they are compressed somewhat when the heads are coupled.' These packing rii'ig's are preferably beveled, as illustrated, so that the parts slide together without injur thereto, see Figs. 10 and 14:.

l prefcrabl provide my improved coupling with a special form of packing ring for the steam pipe. This packing ring shown in detail in Fig. 10, is a modification, and. 'in lOl some respects, an improvement upon the packing ring described in my application Thispacking ring consists of a sleeve-like ring 2a, which is sleeved into a suitable socket 21 provided therefor in the coupling head. The ring 23' is provided with flange-like arms I'M. the arms being preferably provided with annular corrugations, as isdescribed in th use above referred to. The bearing lip ill, for the outer arm 30 of the pat-lazing ring, is preferably adapted tol'it within the socket. and is provided with an outer beveled portion 3;, and an annular groove or seat 'in" which the gasket 33 is arranged. The hear ing ring and the llange 30 are preferably securcd at their inneredges only. as rlearlv appears from the drawing. The heaping ring of the inner flange 30 is preferably the same in structure as that of the outer arm except that the beveled portion 3:? is omitted.

3y thus constructing the packing rings.

llt

the coupling headsreadily slide together.

and, after beingbrought together. the l'v. ilil2. ency of the flange and the pres ure of the. steam form perfect joints. The packing Y ring is preferably retained in its socket b means of the ring ll, which is arranged in a suitable annular groove 35. The ring 34 l3 vided with a drip opening 37. This opening is controlled by the valve 39. the pressure of the steamheing adapted to close the valve against the tension ot' .the valve spring. (hen the steam is otl'. the spring lifts the valve. thereby opening the drip. The valveis arranged in a casing 39. and is held in its open position by the springs 40 arranged under the same.

The steam pipe t; is preferably secured to the coupling head by means of a special connection consisting of a pipe conneetingmemher 41. which is threaded upon the end of the pipe. as is illustrated in Figs. (3 and T. The packing ring socket is provided with a reduced portion 4-), adaptedto receive the ipe connecting member ll. the forward end of the pipe connecting member being arranged to be engaged by the inner bearing lip of the packing ring 28. The pipe connec'ting member is provided with a flange .3. which shoulders against the reduced por-' tion 42 of the socket and is held therein by means of the retaining plate 44-. This plateis pivoted on a threaded pin 45. and is provided with a notch lo adapted to engage the pin 1LT. the pins being provided with thumbserews 4.8 so that the plate may be readily secured or released to secure or re ease the pipe. This aticrds a rapid and secure means oi connecting the steam hose or pipe. which permits its being disconnected or renewed. should occasion require. with little ditliculty. The coupling heads are preferably provided with opening'3 -l9 above the steam passages. so that a circulation of air secured. and the heads prevented from becoming urtduly heated. In the modification shown in Fig. 13. the catches 1Q are omitted. This form is :isfactory. but the form shown as the preferred construction has the advantage of the members coupling with less wear and friction upon each other. Thisinodilied construction, however. possesses the same advantages of the pressure of the -steam serving-to hold the heads together rather than tending to separate them. that is. the pressure of the steam serves to hold the latch members in engagement rather thanto separate them and also thesame advantage of the wedging or clamping action of the faces of the heads upon each other in couplin As it is sometimes desirable to use one of my improvedcouplers in connection with a car equipped with individual couplers, I provide what designate as an emergency head, the same being illustrated in Fig. '12. This preferably con=istsof the head 5 having coupling members 51, 51

pipes therein, hanger and 52, which are adapted to be connected ling-s now generally used. The head is provided with a packing ring adapted to ('(Hltl \illl the packing rings described, and i provided with a hoolt at its inner end. which may he engaged on the latch 11 and with the pivoted latch 54 at its outerend. which may be engaged over the catch 10 with the coup of the male member of the opposite head.

The latch 54- is preferably in the form of a ring. and held in its engaging position by means of the springs; .35. This l1191'"11( head has the advantage of beiug'quick y attached and at the same time it is secure when attached.

lly forn'ting and arranging the parts as I have illustrated and described. I ecure a coupling which is adapted to automatically couple or uncouple on the coupling or nocoupling of the cars. and. at the same time.

it is very secure. The structure is comparativelysimple and economical to manufacture. and is very durable innstx.

I have illustrated and described my improved coupling in detail in the form preferred by me on account of its structural simplicity and economy. I am, however. aware that it iscapa ble of consit'lerable variation in structural details without departing from my invention. and I desire to be undertood as claiming the same specifically as illustrated. as well as broadly.
